firefox-performance-dashboards VS sidebery

> Show me these pages that Firefox doesn't render well.

I'm not doing homework for you. Lots of pages don't render well in Firefox, it's a well known issue which is why it comes up in every thread about Firefox.

> Show me pages that tank Firefox performance.

Firefox in general performs poorly. Again, known long-term ongoing issue. Look at this thread where almost every top-level comment is sceptical that Firefox is even close to Chrome in performance: https://news.ycombinator.com/item?id=36770883

You can find ongoing performance benchmarks between Chrome and Firefox here, and it's not flattering for FF: https://arewefastyet.com

> How many of them will have -webkit-* and other engine-exclusive markup/CSS?

I don't care, at all. It's not my job, as a user, to debug performance problems.

> Firefox updates every 6 weeks, just like Chrome.

Ok? I didn't say anything about update cadence.

The link is terrible. Maybe the article should link to https://arewefastyet.com or maybe the Speedometer selection at https://arewefastyet.com/win10/benchmarks/raptor-desktop-spe...

Well I would wager a guess it's due to consistency. The full site includes a bunch of different benchmarks, with a lot of them having the y axis as execution time in milliseconds. Meaning, lower is better. They probably just wanted to keep that consistency even with tests that use scores. Definitely a bit misleading without the full context. The full site is arewefastyet.com

They do... They just don't have the resources Google does. If you see https://arewefastyet.com you can see that Firefox has been steadily improving in speed, and they have actually recently been working to make react faster.

I filed a bug for that.

Have you tried the Sidebery vertical tabs extension for Firefox?

I am using https://github.com/mbnuqw/sidebery for this now.

I frequently come across GitHub projects that don’t include any screenshots and the project will contain UI elements. I’m wondering if there is a reason why so many don’t include screenshots?

For example sidebery[1] didn’t have it. I use it and it’s great but it’s hard to get a sense of what it does Without actually showing a screenshot.

I don't think so. I use Sidebery and their recommended approach is to edit userChrome.css. It's not too bad and works well. See https://github.com/mbnuqw/sidebery/wiki/Firefox-Styles-Snipp....

I've only had a brief look through Siderbery's code before https://github.com/mbnuqw/sidebery. I'm not really sure where to start with Vivaldi extensions but I have been tempted to look into it. It's chromium, so chrome extensions will work, although Sidebery is sort of a kitchen sink conversion for Firefox and I'm not sure if something similar exists on Chrome.

I don’t think it was ever possible, based on the creator’s comments in this issue.
